Warrant MCP Server

io.github.s0fractal/warrant
local only

Warrant runs on your own machine — the client starts it, so there is no endpoint to ping. 2 035 installs a week from pypi. Last commit 3 Aug 2026.

Record an agent's decisions with reasons anyone can re-execute offline — verify recomputes them.

Warrant — questions

Answers built from our own checks of this server.

Why is there no uptime for Warrant?
Warrant runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package warrant-verify was installed 2 035 times last week.
How do I connect Warrant?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls warrant-verify straight from pypi; nothing to host, nothing to sign up for.
How many people use Warrant?
The pypi package warrant-verify was installed 2 035 times in the last week. Week over week that is +2937%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Warrant open source?
Yes — it is published under the MIT licence, written in Python and 4 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
